Think you can run with the pros? DRL has released a Beta version FPV Simulator designed to work with a FrSky® Taranis X9D transmitter.
Those who don't have one can still try the simulator and get a "limited simulation experience" using their Xbox/Playstation controller or computer's WASD/arrow keys.
The simulator works with Mac OS X and Windows.
